Application filed April 10, 1918. Serial No. 227,725.

To all whom it may concern:

Be it known that I, WILLIAM O. PEAVEY, a citizen of the United States,residing at Ebro, in the county of Clearwater and State of Minnesota,have invented certain new and useful Improvements in Post-PeelinMachines; and I do hereby declare the ollowing to be a full, clear, andexact description of the invention, suchas will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to improvements in 0st or mine stock or timberpeeling mac ines and has for one of its objects the provision of adevice of this character whereby the bark of a log may be readilyremoved by rotating knives and which knives are capable of adjustment toaccommodate logs of different sizes.

Another object of this invention is the provision of means for guidingthe posts to the knives so that they will be in proper position whencoming in contact with the knives.

A further object of this invention is the provision of the cutting meansor knives located in upper and lower pairs and which upper pair issupported in a swinging structure so that ,the upper pair can readilyadjust itself to the post and which is located in rear of the lowerpair. whereby one-half of the bark of the post is removed in advance ofthe other half.

A still further object of this invention is the provision of a logpeeling machine of the above stated character, which will be simple,durable and eflicient, and which may be manufactured and sold at acomparatively low cost.

With these and other objects in view, as will become more apparent asthe description proceeds, the invention consists in certain novelfeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawings, in which:

Figure 1 is a longitudinal sectional view of the post peeling machineconstructed in accordance with my invention.

Flg. is a fragmentary sectional view illustrating the lower cuttingmeans and the post guidemeans associated therewith.

Flg. 3 1s a fragmentary vertical sectional view illustrating the meansof suspending the upper cutting means,

Fig. 4 is a detail sectional view illustratmg the manner of supportingthe guides.

Fig. 5 is .a detail sectional view taken on the line 55 of Fig. 3illustrating the means for permitting adjustment of the upper cuttingmeans.

Referring in detail to the drawings, the numeral 1 indicates a table topsupported by suitable legs 2 which are braced by members 3. The tabletop 1 is provided with a transverse opening 4 in which is mounted atransverse shaft 5. The shaft 5 is journaled in suitable bearings 6carried by the table top 1 and has secured to one end a pulley 7 for thepurpose of receiving an ordinary power belt. A pair of substantiallyfrusto-conical blocks 8 are splined to the shaft 5 and have their wallsconcave, as clearly illustrated in Fig. 2. The blocks 8 have theirapexes disposed in the direction of each other and are urged in thedirection of each other by means of expansion springs 9 mounted upon theshaft 5. The expansion springs 9 have one of their ends disposed againstthe blocks 8, while their opposite ends bear against shoulders 10 formedupon the shaft, providing a construction wherein the blocks may movetoward. each other to accommodate logs of different sizes. The concavefaces of the blocks 8 are provided with grooves in which are positionedarcuate shaped cutting knives 11, and which are secured therein bysuitable fastening elements 12. The knives of one of the blocks arein aline with the knives of the other block so that they cooperate witheach'other in forming substantially semi-circular cutting knives whichwill remove substantially onehalf of the bark from a post 13 when itcomes in contact with the same.

The table top 1 is provided with" longitudinally extending openings 14that communicate with the transverse slot or opening 4 for the purposeof receiving "spaced guide members 15 that are arranged in pa rs uponeach side of the blocks 8. The guide members 15 of each air have theirupper ends beveled in opposite directions, as illustrated at 16, for thepurpose of engaging and conforming to the contour of the post. The guidemembers 15 are slidably supported in hangers or supporting members 17that are secured to the under face of the table top 1 to connect withthe openings 14. The hangers or supporting members 17 are divided intoguideways 18 by means of partitions 19. Expansion springs 20 areloca'ted within the guideways 18 for the purpose of normally urging theguide members 15 upwardly into engagement with the post, but which.permit the guide members to move downwardly within the hangers toaccommodate themselves to difierent sizes of posts. The hangers orsupporting members 17 have journaled therein transversely extendingshafts 21 and the guide members 15 are provided with dots to receive theshafts so that the guide members may move upwardly and downwardlywithout interfering with the shafts. The shafts 21 are also journaled tothe table top 1 and disposed below the same and have mounted thereonfeed rollers 22 which are disposed within the slot or openings 14between the pairs of guide members 15; The feed rollers 22 have teeth orspikes 23 formed thereon for the purpose of biting into the post to feedthe same across the table top 1 upon rotation thereof. One of the shafts21 has a pulley 24 that receives a belt 25 that travels over a pulley'26carried by the shaft 5, whereby upon rotation of the shaft 5, the saidshaft 21 will be rotated therewith. The said shaft 21 also has a pulley27 adjacent its opposite end on which a belt 28 travels. The belt 28passes over a pulley 29 carried by the other shaft 21 so that the othershaft 21 is driven by the first named shaft 21.

Upwardly inclined supporting members 30 are secured to one end of thetable top 1 and have their upper ends disposed in vertical alinementwith the shaft 5. The supporting members 30 carry at their upper endscylindrical extensions 31 which have.

journaled thereon hanger arms 32. The hanger arms 32 are capable ofswinging about the cylindrical extensions 31 and are retained thereon bymeans of nuts 33. A shaft 34 extends through the cylindrical extensions31 and is rotatably supported by the supporting members 30. A belt 35 isconnected to one end of the shaft 34 and to the shaft 5 for the purposeof rotating the shaft 34 with the shaft 5. The

essence moved upwardly and downwardly in relation to the arms 32. Thebearings are held against accidental movement by means of bolts 40. Thebearings 37 have journaled therein a shaft 41 on which are splinedsubstantially frusto-conical shaped blocks 42 that are identical inconstruction'with the blocks 8 and are each provided with cuttingknives. The blocks 42 are urged in the direction of each other by meansof expansion springs 43 mounted upon the shaft 41. The shaft 41 has apulley 44 connected to one end over which travels a belt 45. The belt 45extends over a pulley 46 secured to the shaft 34, whereby upon rotationof the shaft 34, the blocks 42 will be rotated thereby.

In operation, the upper cutting elements are supported in rear of thelower cutting elements as clearly illustrated in Fig. 1. The post 13 isfed onto the table top 1 and into engagement with the lower cuttingelements first by one of the feed rollers 23 and asthe same passes thelower cutting elements substantially one-half of the bark of the post ispeeled or removed, and upon further movement of the post it moves intoengagement with the upper cutting elements which rest thereon bygravitation and remove substantially the other half of the bark of thepost. By having the upper cutting element mounted in the mannerheretofore described, it permits the same to accommodate itself to postsof several sizes. The upper cutting element may also be adjusted uponthe arms 32 by adjusting the location of the bearings 37 with relationthereto.

While 1 have shown and described the preferred embodiment ofimyinvention, it

will be understood that minor changes in construction, combination andarrangement of parts may be made without departing from the spirit andscope of the invention as claimed.

Having thus described my invention what 1 claim is:

1. A post peeling machine comprising a table, upper and lower cuttingelements carried by said table, hangers carried by said table springactuating guide members carried by said hangers for guiding a postbetween the cutting elements, and means feeding the post between thecutting elements.

2. A post peeling machine comprising a table, a shaft journaled to saidtable, substantially frusto-conical blocks splined to said haft, meansurging the blocks in the direction of each other, knives carried. by theblocks, an upper cutting element carried by the table and capable ofswinging movement to accommodate itself to posts of several sizes, andmeans feeding the post into engagement with the knives and with theupper cutting element.

- In testimony whereof I aflix my signature in presence of twowitnesses.
